continued his work with magic hypercubes, achieving during this time: the first perfect magic tesseract (order 16), in April 1999; the first order 32 perfect magic tesseract; the first inlaid magic tesseract (order 6 with inlaid order 3) in October 1999; and the first bimagic cube (order 25), June 2000. In 2004, Hendricks was unable to continue with his mathematical work due to ill health. He died in Victoria in 2007, aged 77.
