A Jacobson Radical Decomposition of the Fano-Snowflake Configuration
Abstract
The Fano-Snowflake, a specific -unimodular projective lattice configuration associated with the smallest ring of ternions (arXiv:0803.4436 and 0806.3153), admits an interesting partitioning with respect to the Jacobson radical of . The totality of 21 free cyclic submodules generated by non-unimodular vectors of the free left -module are shown to split into three disjoint sets of cardinalities 9, 9 and 3 according as the number of Jacobson radical entries in the generating vector is 2, 1 or 0, respectively. The corresponding "ternion-induced" factorization of the lines of the Fano plane sitting in the middle of the Fano-Snowflake (6 -- 7 -- 3) is found to from the natural one, i. e., from that with respect to the Jacobson radical of the Galois field of two elements (3 -- 3 -- 1).
