Rab: This is a rotation of problem #93 (the previous one in Intro to Life and Death set). In the identical problem, connecting at E18 on the 2nd line is allowed. Descending to the 1st line at F19 is allowed in either problem. The 2nd line connection should be allowed in this problem, just like it is in the identical problem, since either way of playing makes unconditional life.
Please provide sequence.
