Michel Marcus: submit sequence of indices of records ?
17:23
Bill McEachen: @Michel my interest stops at finding the connection but perhaps someone else ( my "Q" is always backlogged)

Bill McEachen: my edit crossed with @Amiram, give me a bit of time please
14:50
Amiram Eldar: I think that you mean "positions of records", while Michel checked the record values.
14:57
Bill McEachen: nope, I'm done, can proceed as is
14:58
Bill McEachen: again, failed to refresh, just saw last comment. Please give me time again
15:02
Amiram Eldar: I checked the indices (or positions) of records, and verified your conjecture up to 5*10^7.
15:21
Bill McEachen: great, I will that conjecture back shortly. Thank you again.
