[Poo Sung and Beedassy] The only derangement of the prime 2357 that is an emirp. Note that the concatenation of both primes (23577523) and their reversals (75323257) forms other primes. [Beedassy] 5*7*13*19  2*3*11*17 = 7523, written with the first consecutive primes on the left of the equation and a prime (emirp) with only prime digits on the right. [Capelle] The smallest Honaker prime with all the prime digits: 7523 is the 953rd prime and 7 + 5 + 2 + 3 = 9 + 5 + 3. Note that the latter sum 17 and the concatenation 7523953 are also primes, as are the reversals 3257, 359, 71. [Beedassy] The only prime q of form q=4p+7, consisting of distinct prime digits, with p being also an emirp with distinct digits, (p=1879), of the same form, 4*n+7, (n=468).
