Euler function - oiler function

Japanese: オイラー関数 - おいらーかんすう
Euler function - oiler function

…When m = 6, 1,5 is an irreducible coset. The function φ determined by the number of irreducible cosets modulo m , φ( m ), is called the Euler function. When m and n are mutually prime natural numbers, φ satisfies the relationship φ( mn ) = φ( m )φ( n ), and if is a prime factorization of m , then φ( m ) is given by …

*Some of the terminology explanations that mention "Euler function" are listed below.

m=6のとき,1,5は既約剰余系である。mを法とする既約剰余類の個数φ(m)によって定められる関数φをオイラー関数という。mnが互いに素な自然数であるとき,φはφ(mn)=φ(m)φ(n)という関係を満たし,をmの素因数分解とすると,φ(m)は,で与えられる。…
