COMMENTS
A141326 is a simply generated subsequence of A050791 and by observation it forms a natural measure of the parent sequence. The first several hundred terms of the parent sequence not belonging to A141326 are bracketed into groups with a small integral number of terms ( including 0 ) by the successive terms of the subsequence, A141326.
a(107),a(108) are the first occurrence of 2 consecutive 0's and a(119),a(120),a(121) are the first occurrence of 3 consecutive 0's. This leads to the following conjecture:
<a(n)> -> 0 as n ->inf
where <a(n)> = ( sum m=1,n of a(m) )/n

FORMULA
a(1) = A145383(1) - 1
a(n) = A145383(n) - A145383(n-1) - 1 ; n>1
EXAMPLE
0 = number of terms of A050791 preceding the first term of A141326
1 = number of terms of A050791 between the first and 2nd terms of A141326
2 = number of terms of A050791 between the 2nd and 3rd terms of A141326
