Forty-six is a Wedderburn-Etherington number, an enneagonal number and a centered triangular number. It is the sum of the totient function for the first twelve integers. 46 is the largest even integer that can't be expressed as a sum of two abundant numbers.
46 is the 13th semiprime. 46 is the third semiprime with a semiprime aliquot sum. The aliquot sequence of 46 is (46,26,16,15,9,4,3,1,0).
Since it is possible to find sequences of 46 consecutive integers such that each inner member shares a factor with either the first or the last member, 46 is an Erdős–Woods number.
I have no idea what I just said.
Now here's an interesting fact that proves some people have way too much time on their hands:
In Psalm 46 in the King James Version of the Bible, the 46th word from the beginning is "shake" and the 46th word from the end is "spear"; at the time of publication of the King James Bible, playwright William Shakespeare was 46 years oldIt reminds me a bit of the Kennedy-Lincoln coincidences (In Lincoln's & Kennedy's names the vowels & consonants fall in exactly the same place; Lincoln was shot in a theatre named Ford; Kennedy was shot in a car made by Ford).*
46: the number of mountains in the 46 peaks of the Adirondack mountain range. People who have climbed all of them are called "forty-sixers"; there is also an unofficial 47th peak (uh oh; the forty-sixers may have to join up with the 47 Society).
*John Kennedy was 46 when he was assassinated. Now that's just spooky.
All these amazing facts were gleaned from Wikipedia and Orwell Today.
