Super Pandigital Numbers

A positive number is pandigital in base b if it contains all digits from 0 to b - 1 at least once when written in base b.

A n-super-pandigital number is a number that is simultaneously pandigital in all bases from 2 to n inclusively.
For example 978 = 11110100102 = 11000203 = 331024 = 124035 is the smallest 5-super-pandigital number.
Similarly, 1093265784 is the smallest 10-super-pandigital number.
The sum of the 10 smallest 10-super-pandigital numbers is 20319792309.

What is the sum of the 10 smallest 12-super-pandigital numbers?


超级全数字数

如果一个正整数的b进制表示中出现数字0到b-1每个至少一次,则称其为b进制的全数字数。

如果一个正整数同时是从2n进制的全数字数,则称其为n-超级全数字数
例如 978 = 11110100102 = 11000203 = 331024 = 124035是最小的5-超级全数字数。
类似地,1093265784是最小的10-超级全数字数。
最小的10个10-超级全数字数之和为20319792309。

最小的10个12-超级全数字数之和是多少?
