2012L triposPaper.pdf workedSolutions.pdf and erratum. The erratum fixes an error contained within the worked solution for the last part of question one. Also: the sqrt symbols on page six of the worked solutions are typos and should not be present.
2013L triposPaper.pdf workedSolutions.pdf
2014L triposPaper.pdf workedSolutions.pdf There is a small omission on page 6 of the 2014 worked solution. After the words "and noting that this decomposes to" one should insert (i) a diagram consisting of a number three, surrounded by six twos shaped like a hexagon, surrounded by twelve ones shaped like a hexagon of twice the size, and (ii) the word "plus" following that diagram. This missing diagram accounts for the 27 (27=3+6*2+12*1) that appears near the middle of the same page, after the text "8x8=".
2015L triposPaper.pdf workedSolutions.pdf
2016L triposPaper.pdf workedSolutions.pdf Erratum: Thank you goes to Robin Croft for pointing out that the originally supplied worked solution for 1h(i) was an answer for an earlier question involving two Zarks (not the four Zarks finally settled on for the exam). In addition the answer contained an unrelated typo. All are now fixed with an annotation on the supplied pdf.
2017L triposPaper.pdf workedSolutions.pdf There are unconfirmed reports that the worked solution has lost a factor of two between equations (22) and (23).
