The search for Wieferich prime numbers looked for numbers of the form ap-1 = 1 (mod p2) for a = 2 or 3. The only two known Wieferich primes are 1,093 and 3,511 and there are no other Wieferich primes less than 2 * 1014. The project extended the search limit to 1.25 * 1015, but did not find any new Wieferich primes. 131,429 total ranges (37,424,648,092,395 primes) were checked at an average speed of 621,457 primes per second. 131 near-misses were found.
