Distribution of the remainders when the numbers in this family are divided by n=2, 3,..., 11. (I took into account 94 values, from 14 to 7⋅1028).

A pictorial representation of the table above
Imagine to divide the members of this family by a number n and compute the remainders. Should they be uniformly distributed, each remainder from 0 to n-1 would be obtained in about (1/n)-th of the cases. This outcome is represented by a white square. Reddish (resp. bluish) squares represent remainders which appear more (resp. less) frequently than 1/n.
