See page https://www.rieselprime.de/ziki/Riesel_k%3D1300, 9*2^n1 has Nash weight 1674, and 25*2^n1 has Nash weight 1571

Also see post https://mersenneforum.org/showpost.p...7&postcount=24, some forms like 25*12^n1 and 144*19^n1 have zero weight.
25*12^n1: for even n let n = 2*q; factors to: (5*12^q  1) * (5*12^q + 1) odd n: factor of 13 144*19^n1: for even n let n = 2*q; factors to: (12*19^q  1) * (12*19^q + 1) odd n: factor of 5 Last fiddled with by sweety439 on 20200804 at 23:53

Nash weight seems to be also exist for (a*b^n+c)/d with d>1, see https://stdkmd.net/nrr/prime/primedifficulty.txt, the difficulty is the Nash weight of the form.
