Abstract
Consideration ofL n groups for n even and between 6 ≤n:≤ 20, (60) is consistent with the existence (over a simply reducible (SR) space) of certain similarities in the inner tensor product (ITP) structures associated with -p ≤ 2 [n -1, 1] ⊗ [λ.], or -⊗ [(n/2)2] products, and for general (even)n for [n -1, 1] ⊗ [n - 2, 12] ITPs, but not for ITPs involving higher generalm (p ≤ 3) components, as in [n-1, 1] ⊗ [n-m, m-1, 1].These observations provide considerable insight into the nature of van der Waals (3 ≤ n ≤ 20), metallic-, or “met-carb-” clusters andn = 12, 20 cage molecules analogous to dodecahedrane (a cage,n = 20 molecule) or13C buckminsterfullerene(ane) (n = 60) [A] n , [AX] n clusters, besides allowing for further combinatorial views on higherL n group characters and their associated group algebra. Mathematical insight to date into the nature of general ITPs involvingnon-SR direct sums has proved less fruitful on account of the number of component partitions spanned by specific TTP maps and their associated multiplicities.
