I don't get this part. IIUC, for getting the sextic, the number had to be multiplied by 131^2*106, whereas for the quintic, there is no such fiddling necessary. So the sextic difficulty should be 6 digits larger.
Output by Yafu. With SNFS it cranks out dozens of potential polynomials then downselects to the best three for test sieving. Perhaps B^2 can shed more light on the various steps of that Kabuki dance.
Indeed, I don't understand the values Yafu is printing. My calculations show the quintic with a difficulty of 265.32 and the sextic with a difficulty of 271.57, so there's axn's 6 digits right there.
