One could say, that only blightless functions are interesting, and deserve to be drawn as Euler diagrams.
For the whole geometric analysis, only those with a single bundle are interesting.

Eventually these pages should show an example for each BEC with arity up to 4.


3-ary[edit | edit source]

Of the 22 BECs with arity up to 3 there are 16 whose actual arity is 3.
5 of them are blighted, and 11 are blightless. 5 of them have multiple bundles, and 6 have only one.

4-ary[edit | edit source]

Of the 402 BECs with arity up to 4 there are 380 whose actual arity is 4.
37 of them are blighted, and 343 are blightless. 51 of them have multiple bundles, and 292 have only one.
