Unclear sentence
[edit]The introduction contains this sentence:
"This upper bound is tight up to a constant factor to a construction by de Caen."
I cannot make any sense of the way this is worded. What does
"tight up to a constant factor to a construction" mean? I cannot even guess.
I hope someone knowledgeable about this subject can rephrase this sentence so that its meaning becomes clear.
