Cron job interval larger than 60 mins

[chophouse]

I'm not sure exactly which forum to ask this,so I'm starting here,

I have a cron job I want to execute every 72 minutes. I've researched how to schedule the job for an interval of 60 min or less, but is there a way to specify a minutes interval when the required interval is > 60 ?

I think you can use a multi-entry crontab like this:

0 0,5,10,15,20 * * * cmd-to-run
12 1,6,11,16,21 * * * cmd-to-run
24 2,7,12,17,22 * * * cmd-to-run
36 3,8,13,18,23 * * * cmd-to-run
48 4,9,14,19 * * * cmd-to-run

How would i use that to define an interval of every 72 minutes ? Not sure I understand.

Rubberman has you running the command
on the hour for 12 midnight, 5 am, 10 am, etc.
12 mins after the hour for 1 am, 6 am, ...
24 mins after the hour for 2 am, 7 am, ...
etc.
Very clever.
