In mathematics
[edit]
26 is a composite number. 26 is also a telephone number, specifically, the number of ways of connecting 5 points with pairwise connections.[1]
Group theory
[edit]There are 26 sporadic groups.[2]
The 26-dimensional Lorentzian unimodular lattice II25,1 plays a significant role in sphere packing problems and the classification of finite simple groups.
In religion
[edit]- 26 is the gematric number, being the sum of the Hebrew characters (Hebrew: יהוה) being the name of the god of Israel – YHWH (Yahweh). 26 is also the gematric number for GOD with the corresponding substitutions in English (i.e. A=1, B=2, C=3, and so on)
- In the Tenrikyo religion of Japan, 26 is frequently used, since it marks the lunar calendar date of its founder Nakayama Miki's first divine revelation and also her death.
