| '''Seventy-nine''' is the [[natural number]] following [[78 (number)|78]] and preceding [[80 (number)|80]].
| |
| | |
| ==In mathematics==
| |
| *An [[even and odd numbers|odd]] number
| |
| *The smallest number that can't be represented as a sum of fewer than 19 [[fourth power]]s
| |
| *A strictly non-[[palindromic number]]
| |
| *The 22nd [[prime number]] (the next is [[83 (number)|83]])
| |
| *The smallest prime number ''p'' for which the [[real quadratic field]] '''Q'''[√''p''] has [[class number]] greater than 1 (namely 3)<ref>H. Cohen, ''A Course in Computational Algebraic Number Theory'', GTM 138, Springer Verlag (1993), Appendix B2, p.507. The table lists fields by [[Real quadratic field#Discriminant|discriminant]], which is 4''p'' for '''Q'''[√''p''] when ''p'' is [[modular arithmetic|congruent]] to 3 modulo 4, as is the case for 79, so the entry appears at discriminant 316.</ref>
| |
| *A [[cousin prime]] with [[83 (number)|83]]
| |
| *An [[emirp]], because the reverse of 79, [[97 (number)|97]], is also a prime
| |
| *A [[fortunate prime]]
| |
| *A prime number that is also a [[Gaussian prime]] (since it is of the form <math>4n + 3</math>)
| |
| *A [[happy prime]]
| |
| *A [[Higgs prime]]
| |
| *A [[Kynea number|Kynea prime]] (<math>(2n + 1)^2-2</math>)
| |
| *A [[lucky prime]]
| |
| *A [[permutable prime]], with [[97 (number)|ninety-seven]]
| |
| *A [[Pillai prime]], because 23[[Factorial|!]] + 1 is [[divisible]] by 79, but 79 is not one more than a [[Multiple (mathematics)|multiple]] of [[23 (number)|23]]
| |
| *A [[regular prime]]
| |
| *A prime in a [[Dirichlet's theorem on arithmetic progressions|residue classes]] 4n+3, 8n+7, and 10n+9
| |
| *A [[right-truncatable prime]], because when the last digit (9) is removed, the remaining number (7) is still prime
| |
| *A [[sexy prime]] (with [[73 (number)|73]])
| |
| *The ''n'' value of the [[Wagstaff prime]] 201487636602438195784363
