Query: Follow Up on Detecting Deficiencies: An Optimal Group Testing Algorithm   In a recent volume of Mathematics Magazine (Vol. 90, No. 3, June 2017) there
is an interesting article by Seth Zimmerman, titled Detecting Deficiencies: An
Optimal Group Testing Algorithm. The claim in the summary is contradictory to
well-known facts reported in the group- testing literature, which is easily
verified, beginning with the work by Sobel and Groll (1959), which was cited by
S. Zimmerman himself. Therefore, I feel compelled to offer a number of comments
and clarifications. In addition, I have made some correction of mistaken claim
made by Zimmerman (2017).
