 A273920 Number of 10-tuples of primes in arithmetic progression less than 10^n. 4
 0, 0, 0, 1, 5, 145, 2969 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,5 REFERENCES See A113827. LINKS Table of n, a(n) for n=1..7. EXAMPLE The least 10-tuple is {199, 409, 619, 829, 1039, 1249, 1459, 1669, 1879, 2089}, which explains a(4)=1 (and a(n)=0 for n<4). CROSSREFS Cf.
