Trac #34902: LatticePoset breadth, error in documentation
I got a mail about my posting in year 2017: "However, I read Stephan's
paper differently: He states that breadth k is equivalent to containing
a Boolean lattice with k atoms (but none with k+1 atoms) as a subORDER,
and then states in his Lemma 1 that in the case k=3 this is the same as
subLATTICE."
Hence documentation of `breadth()` in `LatticePoset` containing
This can be also characterized by sublattices: a lattice of breadth at
least `$n$` contains a sublattice isomorphic to the Boolean lattice of
`$2^n$` elements.
must be changed to
This can be also characterized by subposets: a lattice of breadth at
least `$n$` contains a subposet isomorphic to the Boolean lattice of
`$2^n$` elements.
