Groups of order 39

This article gives information about, and links to more details on, groups of order 39
See pages on algebraic structures of order 39 | See pages on groups of a particular order

There are, up to isomorphism, two groups of order $39$, indicated in the table below:

Group	GAP ID (second part)	Abelian?
Semidirect product of Z13 with Z3	1	No
cyclic group:Z39	2	Yes

This is classified by the classification of groups of order a product of two distinct primes in the case with two isomorphism classes since $39=3\cdot 13$, with $3\mid 13-1$.
