Along with deleting those bad primes, please just delete/disable the modulo operator altogether if that hasn't been done already. It obviously isn't implemented correctly, it's not particularly...

I was hoping that factorization could be useful as a search term. The sequences appear to have been added in early February (around the 7th to the 8th), but no mention of that base was made in this...

1058 = 2*23^2, the next double of a square, so maybe look for that?

I haven't had much time to dedicate to this subproject, so I'll release base 24. I feel like I'm holding up its progress.

I think I reached a breakthrough in the case. I collected a random sample of a few of the small composites from the recent batch, and they're all spawned off the spammed product-type entries (e.g....

The script as written does not report factors found via TF (i.e. those less than 10^5). This code fixes that issue (replace lines 85-89 with this code):

Unless you're also immediately posting the Primo certs or doing P-1/P+1 proofs, please don't. Additions like those create extra work for the cert elves and are part of the overall problem.
