Morphisms 0076 \(\to\) 027U

\(\mathrm{I}_{7,0} \to \mathrm{I}_{22,0}\)

Column \(j\) of each matrix gives \(\varphi(e_j)\) in the chosen basis of the target; the subdivisions separate orthogonal summands of the source (columns) and of the target (rows).

Notes

The embeddings of latticedb.summands: each summand of the source maps by \(x \mapsto (x, \ldots, x)\) into a set of orthogonal summands of the target.

Diagonal into the summands \(\{1\} \sqcup \{2\} \sqcup \{3\} \sqcup \{4\} \sqcup \{5\} \sqcup \{6\} \sqcup \{7\}\)

Summand \(j\) of the source maps by \(x \mapsto (x, \ldots, x)\) into the orthogonal summands of the target in set \(j\), which are counted from 1 in the order of the basis.
