will be down at times on those day (and possibly the next). (caldwell@utm.edu) The only known multidigit palindromic prime found by averaging the divisors of a composite number. [McCranie and Honaker] The sum of 37 consecutive primes (30103 = 683 + 691 + 701 + ... + 937 + 941). [Rivera] Solution to the quadratic equation n2 + n + 1 when n is substituted with prime 173. [De Geest] The decimal expansion of the common logarithm of two rounded to five digits. [La Haye] The sum of three consecutive palindromic primes starting with 30103 is a palindromic prime as well (30103 + 30203 + 30403 = 90709). [De Geest] The smallest palindromic prime such that another (370717073) emerges after intertwining it with the digital sum of itself. [De Geest]
