OEIS Sequences

Least n-digit multiple of n such that the r-th digit is prime if r is a prime else it is composite. The location and value of the most significant digit is 1. 0 if no such number exists. A113572

a(n) is the least n-digit number whose k-th digit is prime if k is prime, composite if k is composite, and 1 if k=1. A113574

Array read by antidiagonals: T(m,n) = Sum(1<=i<=m) i * ( n + 2(i-1) )! A211366

Concatenation of the first n entries of the difference sequence of prime numbers (see A001223). A255307

Consider constructing binary words that begin with 0 such that the subword 00, whenever it appears, is followed by 111. Then a(n) counts such words at length n (including those where the string 111 is yet being completed - see Example). A340215
