The smallest reflectable invertible prime and also the
smallest reflectable invertible emirp. [Capelle]
The smallest invertible dihedral prime, the smallest dihedral emirp, the smallest reflectable invertible dihedral prime, the smallest reflectable dihedral emirp, the smallest invertible dihedral emirp and also the smallest reflectable invertible dihedral emirp. Note that a dihedral prime is an emirp iff it is invertible. [Capelle] The sum of first 11 primes ending with 1 is an invertible emirp beginning with 11, (the smallest strobogrammatic prime), i.e., 11+31+41+61+71+101+131+151+181+191+211=1181. [Loungrides]
