Number of companies with LLL abbreviations?

[wb]

Other than searching for 'LLL' on Companies House and IPO (which will only bring up companies/marks that begin with or exactly match 'LLL') is there a way to research how many companies have it as an abbreviation?

For example, finding out how many there are called names such as 'Letter Letter Letter Ltd' or similar?

Could potentially be somewhat useful for LLL valuations.

Cheers!
