The twenty-six (26) is the natural number between twenty-five and twenty-seven . She is straight .

Mathematical meaning

Pierre de Fermat realized that 26 lies immediately between a square number ( ) and a cube number ( ). After a few days he finally succeeded in making it clear with a demanding mathematical proof that this criterion does not apply to any other number. Fermat announced this fact to the mathematician community, but withheld his own evidence, presumably to “test” his colleagues. The reasoning was so complicated, however, that contemporary mathematicians Wallis and Digby, who tried to prove the thesis for themselves, had to give up. ${\ displaystyle 25 = 5 ^ {2}}$ ${\ displaystyle 27 = 3 ^ {3}}$

Religious meaning

The Hebrew tetragram יהוה ( YHWH , German mostly reproduced as Yahweh or Jehovah ), which designates the name of God in the Tanach , forms the sum with the numerical values of the four letters, which are also Hebrew numerals , the sum 26. In Gematria , the Jewish mystical interpretation of letters , therefore “God” can be interpreted as 26.

According to Jewish tradition, Moses is said to have received the Torah in the 26th generation since God's creation .

Others

The Latin alphabet has 26 letters .

It is one of the only two dimensional numbers (the other is 10 ) that string theory is mathematically possible.
