Also, if in a ring \(R\) every element is a sum of two 5-potents and a nilpotent that commute with one another then \(R\cong R_1\times R_2\times R_3\times R_4\) where \(R_1/J(R_1)\) is Boolean and \(J(R_1)\) is nil, \(R_2\cong R_a\times R_b\times R_c\) where \(R_a=0\), \(R_c=0\) and \(R_b/J(R_b)\) is a subdirect product of rings isomorphic to \(Z_3\), \(M_2(Z_3)\) or \(F_9\) with \(J(R_b)\) is nil, \(R_3/J(R_3)\) is a subdirect product of \(Z_5\)’s and \(J(R_3)\) is nil, \(R_4/J(R_4)\) is a subdirect product of \(Z_{13}\)’s and \(J(R_4)\) is nil.</p>}, number={1}, journal={Communications in Mathematics and Applications}, author={Deka, Kumar Napoleon and Saikia, Helen K.}, year={2024}, month={Apr.}, pages={33–42} }
