.

[a-zA-Z]
a-z matches a single character in the range between a (index 97) and z (index 122) (case sensitive)
A-Z matches a single character in the range between A (index 65) and Z (index 90) (case sensitive)
1st Capturing Group
([^#$%^&*()\=\[\]{};':"\\|,.<>\/?]){6,60}
{6,60} matches the previous token between 6 and 60 times, as many times as possible, giving back as needed (greedy)
A repeated capturing group will only capture the last iteration. Put a capturing group around the repeated group to capture all iterations or use a non-capturing group instead if you're not interested in the data
