Various Games Workshop systems such as Necromunda and Mordheim use an anomalously named D66 roll, meaning d6×10+d6. There are 36 possible results ranging from 11 to 66. The D66 is a base six variant of the base ten Percentile die (d100). The D66 is generally a combination of two six-sided dice, often made distinguishable from each other by color, or simply one die rolled twice. The first die represents the tens digit, and the second die the ones digit. For example, a roll of 1 followed by a roll of 5 will give a total of 15, while a roll of 3 followed by a roll of 6 will give a total of 36. The mean result of the D66 is 38.5, and the standard deviation about 17.16.

Should be no problem but for the notation D66 could be interpteted as a 66-sided dice or this base-6 variant.
