 A238852 Right-truncatable, reversible primes in base 100. 8
 2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47, 53, 59, 61, 67, 71, 73, 79, 83, 89, 97, 311, 313, 347, 349, 353, 359, 367, 701, 709, 719, 727, 733, 739, 751, 769, 773, 787, 1103, 1109, 1123, 1163, 1181, 1193, 1301, 1303, 1319, 1321, 1327, 1361, 1777 (list; graph; refs; listen; history; text; internal format)
 OFFSET 1,1 COMMENTS See A238850 for definitions, and A238854 for comments on general context. In base 100, chosen as one of four examples, there are 1552 such numbers. LINKS Stanislav Sykora, Table of n, a(n) for n = 1..1552 Stanislav Sykora, PARI/GP scripts for genetic threads, with code and comments. EXAMPLE The largest number of this type (using hyphens to separate the base 100 digits) is 19-07-93-27-17-37-99-47-19-11.Truncate any even number of decimal digits on its right, and the remaining prefix is still a base-100 reversible prime (e.g., 19079327 and 27930719 are both primes).
