An interesting determinant occurs in the fifth volume of Muir's History1. It is

where n = ½ (p – 1), and ars is the smallest positive integer such that

rars = s (mod p), (1) p being any odd prime number. It is evident that each element ars is unique and non zero. For p = 5, 7, 11 the determinants are

(2) respectively, and their values are

– 5 , 72, 114.
