Abstract

First we present several properties of the prime 73 and its reverse 37. Next, we introduce the Sheldon conjecture stating that 73 is the only prime satisfying two specific properties. Later, we give an idea of the proof of the conjecture given by Pomerance and Spicer. Finally, we consider Sheldon numbers defined on integer sequences
