This directory contains proof files for Pépin tests on some of the smaller, incompletely factorised Fermat numbers, from F14 up to F29. Further proofs beyond F29 are major amounts of computation and may be made available, if possible.
Pépin’s test is that Pn = α½(Fₙ–1) ≡ –1 mod Fn, if and only if Fn is prime; customarily base α = 3 is used for the test. Théophile Pépin initially proposed base 5 (and also 10), however François Proth showed base 3 also met the theorem’s criteria and this became the preferred base. As no Fermat numbers beyond F4 are known to be prime, any composite Fermat number when tested will leave behind a residue modulo Fn ≢ –1.
Fermat numbers grow quickly and are difficult to factorise, however, so that the Pépin test is only practical up to F30 at this point in time; it may become possible to extend the test to F33 at some future point relatively close to the time of writing. Among these ‘smaller’ Fermat numbers Fm for m < 33, seven composite Fermat numbers are fully factored (5 ≤ m ≤ 11), two composite Fermat numbers are not factorised at all (m = 20 and 24), and seventeen Fermat numbers possess a large, composite cofactor (12 ≤ m ≤ 30, thus excluding m = 20, 24, 31, 32). Beyond F32, the next Fermat numbers with partial factorisations are F36 to F40. An extension of the Pépin test first devised by Hiromi Suyama in 1984 and subsequently modified by Hendrik W. Lenstra, Jr., allows the compositeness of a cofactor to be tested, and some of these results are shown below.
The Pépin test was first tested on eight of the smaller Fermat numbers of unknown character in the twentieth century, proving each to be composite, and at the gentle pleadings of Gary Gostin I have compiled a historical account of these tests, with verifications of all results using his very useful program, cofact. He also provided his proofs of F27 and F28 in the meantime before my own PRP run of F27 was complete (our results agreed with one another, however his proof is also a smaller download).
The thirteen proofs up to F26 were generated using George F. Woltman’s Prime95/mprime software, version 30.10 (and revisions), usually on a single core of a MacBook Pro. (Owing to bots continually trying to download the larger proofs, direct links are only provided for the first few files up to F20; all sixteen are available at the URLs listed.) The proofs were generated using the following “worktodo” lines (and a little edit to the source was needed to generate the three smallest proofs):

One or two additional cores were added for the PRP runs on F24 and above; the times could have been substantially improved by using even more processing power!
When used for certification, proof files allow rapid construction of the final residues (about 0.2% computing effort for power 9 compared with the full run), for use in double-checking the compositeness of the large cofactor, or the compositeness of F20 and F24. The proof power reduces the number of squarings required to generate the residue from the proof:
squarings F14 512 F15 1024 F16 2048 F17 4096 F18, F19 8192 F20, F21 16384 F22, F23 32768 F24, F25 65536 F26 131072
Usually the final residue is not provided to the certifier, but a server retains it to verify the construction; here, these proofs contain the final residues.
Finally, Gary B. Gostin’s cofact program was used to run Pépin tests on all Fermat numbers up to F25, confirming the proof residues, and generate full information on the state of the cofactors. If (or when) further factors for these Fermat numbers are discovered, cofact can be used to quickly verify the status of the newly found cofactor, which could potentially be a very large prime: the current largest-known prime M82,589,933 is larger than F26 but smaller than F27. This can be done in a fraction of the time compared with the computation for the Pépin test.
After calculating the Pépin residue modulo Fm and displaying a quartet of smaller residues (including Selfridge–Hurwitz residues), cofact calculates three quantities and reports their associated residue quartets:
(This residue modulo Fm is saved in full in the first part of the proof file, allowing a direct comparison. In the parlance of Prime95, this is a ‘type 5’ residue, or for the case of unfactorised Fermat numbers F20 and F24, a ‘type 1’ residue, while the Pépin test yields ‘type 2’.)
So if the Pépin test plus one yields zero modulo Fm then Fm is prime; if the Suyama (A – B) modulo C is zero, then the cofactor C is prime. There is also a test for whether the cofactor C is a prime power, which returns a gcd of 1 if it is not (adding this to later versions of cofact was one of my suggestions to improve the program).
First, some “sanity checks”:
F2 = 22² + 1 = 17 is small enough that the Pépin test can be performed by mental arithmetic in several different bases.

F5 = 22⁵ + 1 = 4,294,967,297 is the first composite Fermat number, so here we may also use the Suyama extension to test the primality of the larger factor. The quantities P5, A, and B (all modulo F5), and (A – B) mod C, are non-trivial pen and paper calculations (a calculator handling 20-digit integers and modulo arithmetic should allow confirmation of any individual calculation).
Thus F5 is composite, but the cofactor obtained by dividing by 641 is prime.
Note, that as these computed moduli residues are ~ 232 or less, thus each of the Selfridge–Hurwitz residues are identical with the hexadecimal modulo 264 residue.

For the next four tests on F8, F11, F12, and F16, we should expect cofact to return the known prime cofactors of 62 and 564 digits and two large composite cofactors respectively.

The full logs for cofact on each of F1 up to F26 have been placed at fermat/cofact.log.
The full logs for mprime on F0 up to F26 are likewise at fermat/mprime.log; the log excerpts below are slightly abbreviated and presented as proof of work.
A page of details and references on the ‘smaller’ Fermat numbers (which I am arbitrarily defining as including up to F32) is to be found at fermat/small.
