[seqfan] Re: A073853: Four more terms

[Charles Greathouse]

My code ran for 12 hours, agreed with John's results, and found 6 further terms:
234365843350, 266484243960, 285357252641, 426388494035, 975986718040,
1505420538689

I hope I'm not stepping on any toes by submitting all the terms, of
course crediting Zak and John for theirs?
