I turned off the merge detection to let a sequence run down to a prime and it broke on 81 (3^4). Here's an example using 33391084425, with "detect_merge = false" Code: $./aliqueit -i 0 33391084425 33391084425 Reading config file... Precalcing primes for trial factoring...

ERROR: factor not prime: 1 Note: This is from a clean d/l from GitHub. I made no edits to this source, which is why you can see the "t dri" extraneous characters.
