%N Values of c such that (c+9*b)*Prime(n)#-1 is the least prime such that (c+k*b)*Prime(n)#-1 is prime for k=0 to 9 with c+9*b < Prime(n)# , or 0 if no solution. Prime(n)#=n-th primorial
%C b=A188367(n), c*Prime(n)#-1 is the first of an arithmetic progression of 10 primes or more.
%C I use PFGW program from primeform group to generate the primes and my own sieve to find the least sum c+9*b for an arithmetic progression of at least 10 primes, all primes are certified primes by PFGW program.
%e 13#=30030, 30030*653-1=19609589 , 289*30030=8678670
%e 196095899+k*8678670 is prime for k=0 to 9 for n=6 c=653
%e and b=289
%Y Cf. A188367.
