The number 69,105 was used as an in-joke at the computer game manufacturer Infocom. It has occasionally appeared in later computer games as a tribute to Infocom.

## Significance of the number

The number 69,105 makes a number of appearances in Infocom games. Nick Montfort, in his book Twisty Little Passages (ISBN 0-262-13436-5), suggests that the number was chosen not only because 69 is the common name of a sexual position, but also because in its written form 69,105 falls naturally into two parts with an unusual relationship:

This property was pointed out in a version of the Jargon File dating back at least to 1982. Commenting on the ("Exclusive to MIT-AI") usage of 69 as a generic "large quantity", Guy L. Steele said, "I don't know whether its origins are related to the obscene interpretation, but I do know that 69 decimal = 105 octal, and 69 hexadecimal = 105 decimal, which is a nice property."[1]

The same natural relationship applies to 1,001; 2,002; 3,003; 4,004; 5,005; 6,006; 7,007; 64,100; 65,101; 66,102; 67,103; and 68,104.

## In mathematics

69105 is the third 23036-gonal number and the fifth 6912-gonal number. It is also the 17th 510-gonal and the 15th 660-gonal number.
