Super lucky tickets

In order for the spacecraft to take off, each crew member must be given a ticket. Each ticket must have a sequence of $n$ digits, where $n$ is an even positive number.

Daniil considers a ticket to be super lucky if two properties are true:

• The sum of the first $n/2$ digits is equal to the sum of the last $n/2$ digits.

• The sum of digits in even positions is equal to the sum of digits in odd positions.

Help Daniil count the number of different super lucky tickets.
