The 36 officers problem is a puzzle proposed by Swiss mathemacian Leonhard Euler in 1782.
The problem asks if it is possible to arrange six regiments consisting of six officers each of different ranks in a 6x6 square so that no rank or regiment will be repeated in any row or column.
is the smallest number which can be expressed as the sum of two primes in four ways, and also the smallest number to be surrounded by numbers with the same number of divisors (4): 33 = 3 x 11; 34 = 2 x 17; 35 = 5 x 7 is the smallest number which is the sum of pairs of distinct odd primes in four ways: 36 = 5 31 = 7 29 = 13 23 = 17 19 is the smallest integer (besides 1) being both a square and a triangular number.
is the smallest number to have 9 different factors: 1, 2, 3, 4, 6, 9, 12, 18, and 36.
Leap days number 100 (one every four years) - 4 (one every hundred years) 1 (one every four hundred years), so there are 97 leap days every 400 years.
The probability of being born on February 29 is therefore In numerology, 29 is a very unlucky number and indicates uncertainties, treachery and deception from others.
It was initially developed as an exclusionary language: a way to encode text so that messages could only be read by the initiated...
Example sentence: is a Fibonacci and an heptagonal number.
Palindromic dates are the same when read backward and forward; the first ones are: 10/02/2001, 01/02/2010, 11/02/2011, 02/02/2020, etc.
If leap years occurred once every four years, it would be, but there are a couple of additional rules for determining if a year is a leap year.
If it is divisible by 100, it is not a leap year, but if it is divisible by 400, then it is a leap year (for example, 1900 was NOT a leap year because it is divisible by 100.

It is so named because God would only need the smallest number of moves to solve a cube! Nevertheless, theoretical work suggests that God's Number could be in the 'low 20s'.26 has also a special divine significance in Gematria because it is the sum of the letter-values of the 'Tetragrammaton', the Hebrew biblical name of God ( יהוה Yahweh): Yod Heh Wau Heh = 10 5 6 5 = 26 The diagram above shows the 'Tetragrammaton' written in Phoenician (blue script), Aramaic (red script) and modern Hebrew (black script).
