Group Members:Alan LiddellAnna CaldwellCarolyn CalderbankTechnically the name for work # 36 is system VIb, but our group, indfing the name a tad too bland, decided to rename the thing Snakes on a Plane ( as there are indeed snakes on a geometric plane). These snakes strictly interact with each other using only diagonal glide reflections; there are no reflections and we saw no rotations so we assumed that the work had symmetry pg. However there are indeed 180 degree rotations making the correct classification of this work pgg.For work #53 we did not come up with an extremely interesting name or even an amusing one, nor were we able to correctly determine its work's classification. Our group noticed and identified the base unit as half of one of the black men and red men, inclined at an angles so that when reflected create rotations with an order of three. Our immediate classification of this work was p3m1 as there were reflections and rotations of order 3, however in the grouping of p3m1, all of the rotational axis line up on the lines of reflection this was unfortunately not the case with work #53, where things also lined up to create rotations of order 3 that were not on lines of symmetry. Thus work #53 turned out to be p31m.
