 A131759 Numbers n such that if for every digit K of n you calculate prime(K)^K and sum for all digits you get n (assumes that prime(0)^0 = 1). 0
 2420, 2421, 3602725959565 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 LINKS EXAMPLE 2421 is in the sequence because prime(2)^2 + prime(4)^2 + prime(2)^2 + prime(1)^1 = 3^2 + 7^4 + 3^2 + 2^1 = 2421.
