How to memorise ASCII

You don't need to memorise ASCII as there is a handy chart available by typing man ascii in a Terminal. However, you may find it useful to remember some fun facts about ASCII.

Blocks of 32 are useful. 32 is 2⁵ (2 raised to the power 5) and a block of 32 is enough to represent all 26 common english letters plus some extra stuff.

ASCII is a coding for the first 128 numbers. 0 to 127.

the consultation makes references to "Autumn Statement" and "the Chancellor" (executive summary, para 2, page 5) without further explanation or reference to these documents and roles. That detracts from the clarity of the consultation document.

executive summary, para 3, page 5, asserts that the Land Registry underpins a valuable property market, without qualifying that by explaining that not all land (or even owned land) is in the registry.
