references in English, number theory, permutations

Topics on number theory in other texts.  

[JH_GUIDE] /

[GP_MDSCS] (211-237 a different focus) 

[WBOOK] Discrete Mathematics/Number theory

[VK_DSLN] 15-20

[RP_CDS] 37-41

The bracket expressions refer to References in English main page.

None of the above references contains appropriate permutation-related material. So I am posting an extra link.
