Forty-nine is the square of seven and is therefore the fourth squared prime number.
The aliquot sum of forty-nine is 8. and this number has an aliquot sequence of (8, 7, 1, 0 ).
49 is the 8th composite number in the 7-aliquot tree.
The sum of the digits of the square of 49 (2401) is the square root of 49.
49 is the first square where the digits are squares. In this case 4 and 9 are squares.
It appears in the Padovan sequence, preceded by the terms 21, 28, 37 (it is the sum of the first two of these).
Along with the number that immediately derives from it, 77, the only number under 3 digits not having its home prime known (as of late 2010).

I was expecting "49 is my house number"
50 is...an even number.
