With the tools at hand, I can extend this to: %S A067091 2,2,329,4101,4919,5737,6556,7374,8193,9012,9830,10649,11467,12286,13104, %S A067091 13923,14741,15560,16378,17197,18015,18834,19652,20471,212899 This corrects the last value in the current sequence. I'm sure it would be no challenge to an MMa artist to take this out to full length.
