 A152962 Beginning of the first maximal chain of primes with n links (n+1 members). 7
 29, 5, 13, 61, 417037, 2153, 4580041 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS For definitions see A152658. The prime indices of the terms are 10, 3, 6, 18, 35153, 325, 321150. Is this sequence finite, i.e. is the length (count of members) of chains of primes bounded? LINKS Carlos Rivera, The prime puzzles & problems connection, Puzzle 463 EXAMPLE First maximal chain of primes with one link (two members) is 29, 31; the linking prime is 631. CROSSREFS Cf. A152658 (beginnings of maximal chains of primes), A152735 (count of links in n-th maximal chain of primes), A119487 (primes of the form i*(i-th prime) + (i+1)*((i+1)-th prime), linking primes), A152865, A152866, A152867, A152868, A152869, A152963, A152964.
