Upside-down numbers

[milagros317]

Certain numbers are the same upside-down. The most famous is 69, but also 181, 808, 6119, and 1961 (the last upside-down year until 6009).

A six digit upside-down number can even be written with its comma: 106,901 regarding the commas as movable from top to bottom after turning the number upside down.

This thread is for posts in which your number of posts is an upside-down number.

It is sad that I missed a lot of these before today. 🙁
