I think the Mark 20 may have been the armor that Pepper destroys (and kills Killian with) at the end of IM3, due to its resemblance to the Mark 7. Either that or the Mark 21, which is also similar. It couldn't have been the Mark 31 since that armor was ripped apart by several Extremis-enhanced super-soldiers before exploding in their faces.
