The number of combinations of six numbers that can be made from seven numbers will depend on if you can repeat numbers. In all there are over 2,000 different numbers that can be made.
There is 1 combination of all ten numbers, 10 combinations of one number and of nine numbers, 45 combinations of two or eight numbers, 120 combinations of three or seven numbers, 210 combinations of four or six numbers and 252 combinations of five numbers. That is 1023 = 210 - 1 in total.
There are: 7C6 = 7
the first digit can be any of the seven numbers, the second can be any of the remaining 6 etc so there are 7 x 6 x 5 x 4 x 3 x 2 x 1 combinations. This is known as "factorial 7" and is normally written "7!" and is 5040.

There are 7 combinations. Each combination excludes a different one of the seven numbers.

Revise your question, it makes no sence.

Start with the factors. Multiply combinations of three prime factors, then combinations of five, then seven, etc. All generated numbers will be guaranteed to have an odd number of prime factors.
any 4 from 7 is 35, in any order is 35 x 24 ie 840
8x7x6x5x4x3x2 or 40320 * * * * * That is totally incorrect. There are only 8 combinations: one with each of the 8 numbers missing. In a combination the order does not matter so 1234567 is the same as 1236547 or 7643125 etc.
You have seven different digits (symbols) to choose from, so you can form seven different one digit numbers and 7×7=72=49 different two digit numbers.
Seven has two syllables, the rest have one.
