COMMENTS

tau(n) mod 691 appears to be almost evenly distributed between 0 and 690 - 2 through 690 each occur approximately 1/691 of the time; 0 occurs slightly more than that and 1 occurs slightly less. However, consecutive values that are congruent mod 691 are predominately congruent to 0.

Jud McCranie: Add a note about these numbers.  Maybe more details later.

N. J. A. Sloane: Given all the zeros, we can allow a large DATA section

Jud McCranie: Do you mean that the table is too big?  What do you mean by "too early" - don't add a table until the sequence is accepted?  Also, I forgot to name it with "b".

Michel Marcus: data is too big; b-file is too early ?

EXAMPLE

Ramajuan tau A000594(1045217422) == A000594(1045217423) == A000594(1045217424) == A000594(1045217425) == 269

so 269 is in the sequence, corresponding to 1045217422 in A337916.
