 OFFSET 1,1 LINKS Hieronymus Fischer, Table of n, a(n) for n = 1..40 FORMULA a(n) > 10^floor((sqrt(8*n+1)-1)/2). min(a(k), k>=n-1) <= A079397(n-1), n>0. a(n) >= A035244(n), n>0. EXAMPLE a(1)=2, since 2 is a prime has 1 prime substring (2). a(2)=13, since 13 is prime and has 2 prime substrings (3 and 13) CROSSREFS Cf.
