"Between 10^(n-1) and 10^n" is equivalent to saying "with n (decimal) digits".
A prime nonuplet is a sequence of 9 consecutive primes (p1, ..., p9) of minimal diameter p9 - p1 = 30.
Terms a(1)-a(11) computed from b-file a(1..651) for A257125.
Apart for n = 1 (cf. EXAMPLE), so far the last term of all the nonuplets has the same number of digits as the initial term.

			a(1) = 1 because 7 is the only single-digit prime to start a prime nonuplet, i.e., member of A257125. (All other members of this nonuplet have 2 digits.)
a(2) = 3 because 11, 13 and 17 are the three 2-digit primes to start a prime nonuplet.
a(3) = 0 because there is no 3-digit prime initial member of a prime nonuplet.

Cf. A257125 (initial members p of prime nonuplets (p, ..., p+30)), A022545 - A022548 (idem, specifically for each of the four possible patterns).

Cf. A350825 - A350828: similar for quintuplets, sextuplets, septuplets and octuplets.

(D(v)=v[^1]-v[^-1])( [setsearch(A257125,10^n,1) | n<-[0..12]] ) \\ where A257125 is a vector of at least 3660 terms of that sequence.

A257124 Initial members of prime septuplets.
