4**21 = 4,398,046,511,104. If each of those array elements took just 1 byte that would need 4000GB (or 4TB) of ram.
But each element of a Perl array requires a minimum of 32bytes on a 64-bit system, so that increases the programs memory requirement to at least 32,000GB.
And that's before you multiply by 197!
Even today, very few computers can access Terabytes of memory -- the latest greatest SkyLake will only address 128GB.
The bottom line is that you are going to have to tackle your problem a different way.
If you can describe what you are trying to do -- in computer terms, with a minimum of bio-lingo -- there is probably an approach that will allow you to achieve it without needing £432,000 worth of memory and a processor that can address it; if such an animal currently exists, it would be in the $millions price range.
