We cons.der algebras.with bas.s.numerated by elements.of a group G. We fix a function f from G × G to a ground field and give a multiplication of the algebra which depends.on f. We s.udy the bas.c properties.of s.ch algebras. In particular, we find a condition on f under which the corres.onding algebra is.a Leibniz algebra. Moreover, for a given s.bgroup G of G we define a G-periodic algebra, which corres.onds.to a G-periodic function f, we es.ablis. a criterion for the right nilpotency of a G-periodic algebra. In addition, for （7 = Z we des.ribe all 2Z- and 3Z-periodic algebras. s.me properties.of nZ-periodic algebras.are obtained.

This.article pres.nts.the mas. and heat trans.ort as.ects.in vis.oelas.ic nanofluid flows.under the pres.nce of velocity s.ip conditions. To explore the nonNewtonian behavior, a Maxwell vis.oelas.icity-bas.d micropolar is.cons.dered. Moreover, a porous.medium s.turates.the s.retching s.eet. A s.t of s.milarity variables.is.introduced to derive the dimens.onles. ordinary differential equations.of velocity, concentration, and temperature profiles. The numerical s.lution is.computed by us.ng the MATLAB bvp4c package. The s.lient flow features.of velocity, concentration, and temperature profiles.are des.ribed and dis.us.ed through various.graphs. It is.obs.rved that with an increas. in the s.ip parameter, the micro-rotation velocity als. increas.s. The temperature of nanoparticles.gets.maximum values.by varying the vis.oelas.ic parameter and the poros.ty parameter while an oppos.te trend is.noted for the micro-rotation parameter. The local Nus.elt number and the local s.erwood number increas. by increas.ng the vis.oelas.ic parameter, the poros.ty parameter, and the s.ip velocity parameter. The graphical computation is.performed for a s.ecified range of parameters. s.ch as.0 ≤ M ≤ 2.5, 0 ≤σm ≤ 2.5, 0 ≤ K1 ≤ 1.5, 0.5 ≤ Pr ≤ 3.0, 0 ≤σ≤ 1.5, 0.5 ≤ s. ≤ 2.0, 0.2 ≤ Nb ≤ 0.8, and 0.2 ≤ Nt ≤ 0.8.
