## Description
|
|
<section id='description'>
|
|
Consider the alphabet A made out of the letters of the word "project": A={c,e,j,o,p,r,t}.
|
|
Let T(n) be the number of strings of length n consisting of letters from A that do not have a substring that is one of the 5040 permutations of "project".
|
|
|
|
T(7)=77-7!=818503.
|
|
|
|
|
|
Find T(1012). Give the last 9 digits of your answer.
