Comments

The continued fraction of the number obtained by reading A359456 as a binary fraction.

Except for the first term, the only values that occur in this sequence are 1, 2, 3, 4 and values 2^A359458(m) - 1 for m > 2. The probabilities of occurrence P(a(n) = k) are given by:

P(a(n) = 1) = 1/3,

P(a(n) = 2) = 1/12,

P(a(n) = 3) = 1/3,

P(a(n) = 4) = 1/12 and

P(a(n) = 2^A359458(m)-1) = 1/(3*2^m) for m > 1.
