Nice table Larry!

One question and two notes

Q: What range of n is involved in computing the weight?

N1: Since we are not 15k anymore we can try k's not divisible by 15. I remember before you mentioned several. In fact from time to time I still work on one of them, k=67773, but I found no reportable primes yet.

N2: There was a program somewhere around to compute Nash/Robinson weights. Just to fill the table but they are not so helpful in finding prolific k's...
