We show that a Magma implementation of Joux\'s new L[1/4] algorithm

can be used to compute discrete logarithms in the 1303-bit finite field

F_{3^{6*137}} with very modest computational resources.

Our implementation illustrates the effectiveness of Joux\'s algorithm

for computing discrete logarithms in small-characteristic finite

fields which are not Kummer or twisted-Kummer extensions.
