For instance, after patching with #11165: {{{ sage: Partition(core=[2,1],quotient=([],[1,1,1,1,1,1,1])) [4, 3, 2, 1, 1, 1, 1, 1, 1, 1, 1] sage: Partition(core=[3,2,1],quotient=([],[1,1,1,1,1,1,1])) ERROR: An unexpected error occurred while tokenizing input The following traceback may be corrupted or invalid The error message is: ('EOF in multi-line statement', (3247, 0)) --------------------------------------------------------------------------- IndexError Traceback (most recent call last) /Volumes/Scratch/Users/duser1/sage/ in () /Users/duser1/sage/local/lib/python2.6/site-packages/sage/combinat/partition.pyc in Partition(mu, **keyword) 262 return from_exp(keyword['exp']) 263 elif 'core' in keyword and 'quotient' in keyword and len(keyword)==2: --> 264 return from_core_and_quotient(keyword['core'], keyword['quotient']) 265 elif 'core' in keyword and 'canonical_quotient' in keyword and len(keyword)==2: 266 raise NotImplementedError /Users/duser1/sage/local/lib/python2.6/site-packages/sage/combinat/partition.pyc in from_core_and_quotient(core, quotient) 314 new_w = [] 315 for i in range(length): --> 316 new_w += [ w[i][j] + length*quotient[i][j] for j in range(len(quotient[i]))] 317 new_w += [ w[i][j] for j in range(len(quotient[i]), len(w[i])) ] 318 new_w.sort() IndexError: list index out of range }}} works in the first case, fails in the second. the code is also badly documented. patch coming shortly. ```apply```: - [attachment:trac_11412-partition_creation_from_core_quotient_big-pod.patch] - [attachment:trac_11412-partition_from_core_quotient-review-fh.patch] ",defect,closed,critical,sage-4.7.1,combinatorics,fixed,partition core quotient,mhansen hivert,,N/A,Florent Hivert,Paul-Olivier Dehaye,sage-4.7.1.alpha3,#11165,
