The journal editors and authors agreed to fully retract the article:
Businaro, Felipe Alvarez, & Bussamra, Flávio Luiz de Silva. (2020). On the sparsity of linear systems of equations for a new stress basis applied to three-dimensional Hybrid-Trefftz stress finite elements. Latin American Journal of Solids and Structures, 17(7), e307. Epub September 28, 2020. https://doi.org/10.1590/1679-78256124
This is due to several unnoticed and unintentional problems with the formulae presented in multiple places and pages across the whole article that were caused at the copyediting stage after the author's intermediary and final proof.
