A bit of prime (noch nicht übersetzt)
Problem 734
The logical-OR of two bits is 0 if both bits are 0, otherwise it is 1.
The bitwise-OR of two positive integers performs a logical OR operation on each pair of corresponding bits in the binary expansion of its inputs.
For example, the bitwise-OR of 10 and 6 is 14 because 10=10102, 6=01102 and 14=11102.
Let T(n,k) be the number of k-tuples (x1,x2,⋯,xk) such that
- every xi is a prime ≤n
- the bitwise-OR of the tuple is a prime ≤n
For example, T(5,2)=5. The five 2-tuples are (2, 2), (2, 3), (3, 2), (3, 3) and (5, 5).
You are given T(100,3)=3355 and T(1000,10)≡2071632(mod1000000007)
Find T(106,999983). Give your answer modulo 1000000007
