Multiplicative Order

The multiplicative order $o(g,p)$ of a number g modulo p, (g and p coprime), is the smallest integer k such as:
$g^k=1\text{ modulo p}$


For instance, $o(10,73)=8$

For how many prime numbers p $<4\times {10}^8$ the multiplicative order $o(10,p)<100$?

Answer format: count,sum

Example: 55,11573 for a limit of 1000
