Kevin Ryde: Yes.  Whatever convenient key to accumulate, and contemplate the target "smallest" of the maximums after.

a(n) = k is the smallest n-digit k for which A046810(k) = A065851(n).

a(n) has its relevant digits sorted and not beginning with 0, and may or may not be one of the primes (it is for n = 1 to 7, but not at n = 8).
