It is a modified double-Gauss, or modified Xenotar configuration lens, which added a negative image flattener for the rearmost element, cemented to the positive element that would be the last element in a double-Gauss configuration. It is rather interesting to note that Summicron 35mm ASPH is very similar to Nikkor-S 35mm 1:1.8, with an exception of a negative element as the first element instead of a positive element. The rearmost negative meniscus element supposedly plays the same role as the Nikkor. It is interesting that a nearly identical lens pops up over 30 years after the original design.
