%N a(n) = concatenation of 1,2,3,...,n mod prime(n).

%e The concatenation of the first 4 integers is 1234. The fourth prime is 7. Therefore a(4) = 1234 mod 7 = 2.

%t a = {}; b = {}; For[n = 1, n < 80, n++, a = Join[a, IntegerDigits[n]]; AppendTo[b, Mod[FromDigits[a], Prime[n]]]]; b

%Y Cf. A095244.

%O 1,3
