We first establish three Ramanujan type congruences. Then many infinite families of congruences are presented. Finally, we propose two conjectures on the congruences for lsi1" class="mathmlsrc">6301950&_mathId=si1.gif&_user=111111111&_pii=S0022314X16301950&_rdoc=1&_issn=0022314X&md5=80fd073b673319438f9f3cd71a6c610c" title="Click to view the MathML source">b(n) modulo lsi2" class="mathmlsrc">6301950&_mathId=si2.gif&_user=111111111&_pii=S0022314X16301950&_rdoc=1&_issn=0022314X&md5=cd47c3c14f14f38fcdbda6ff225b7325" title="Click to view the MathML source">49,81 and 243.
