  "abstract": "We propose a novel neutrino mixing pattern in terms of only two small integers 1 and 2 together with their square roots and the imaginary number $i$. This ansatz is referred to as the \"tetra-maximal\" mixing because it can be expressed as a product of four rotation matrices, whose mixing angles are all \\pi/4 in the complex plane. It predicts \\theta_{12} = \\arctan(2-\\sqrt{2}) \\approx 30.4^\\circ, \\theta_{13} = \\arcsin[(\\sqrt{2}-1)/(2\\sqrt{2})] \\approx 8.4^\\circ, \\theta_{23} = 45^\\circ and \\delta =90^\\circ in the standard parametrization, and the Jarlskog invariant of leptonic CP violation is found to be {\\cal J} = 1/32. These results are compatible with current data and can soon be tested in a variety of neutrino oscillation experiments. Implications of the tetra-maximal neutrino mixing on the decays of doubly-charged Higgs bosons H^{\\pm\\pm} -> l^\\pm_\\alpha l^\\pm_\\beta (for \\alpha, \\beta = e, \\mu, \\tau) are also discussed in the triplet seesaw mechanism at the TeV scale, which will be explored at the upcoming LHC.",
